Exercise 21 Page 424

Find the intervals in which the values of the functions increase as the x-values increase.

Table:

Function Increasing Interval
f(x) x>0
g(x) x<0
Practice makes perfect

To find the increasing interval, we will scan the graph from left to right.

The violet arrows shows increasing intervals of the functions. From left side of graph to x=0 & → && g is increasing From x=0 to right side of graph & → && fis increasing For all x-values less than x=0, g will be increasing. Additionally, for all x-values greater than x=0, f will be increasing.

Function Increasing Interval
f(x) x>0
g(x) x<0
